It is no use to throw a good thing

It was just like so many children. Sir Dinadan was so proud of his exploit that he could not keep from telling over and over again, to weariness, how the immortal idea happened to occur to him; and as is the way with humorists of his breed, he was still laughing at it after everybody else had got through. He was so set up that he concluded to make a speech -- of course a humorous speech. I think I never heard so many old played-out jokes strung together in my life. He was worse than the minstrels, worse than the clown in the circus. It seemed peculiarly sad to sit here, thirteen hundred years before I was born, and listen again to poor, flat, worm-eaten jokes that had given me the dry gripes when I was a boy thirteen hundred years afterwards. It about convinced me that there isn't any such thing as a new joke possible. Everybody laughed at these antiquities -- but then they always do; I had noticed that, centuries later. However, of course the scoffer didn't laugh -- I mean the boy. No, he scoffed; there wasn't anything he wouldn't scoff at. He said the most of Sir Dinadan's jokes were rotten and the rest were petrified. I said "petrified" was good; as I believed, myself, that the only right way to classify the majestic ages of some of those jokes was by geologic periods. But that neat idea hit the boy in a blank place, for geology hadn't been invented yet. However, I made a note of the remark, and calculated to educate the commonwealth up to it if I pulled through. It is no use to throw a good thing away merely because the market isn't ripe yet. Now Sir Kay arose and began to fire up on his history-mill with me for fuel. It was time for me to feel serious, and I did. Sir Kay told how he had encountered me in a far land of barbarians, who all wore the same ridiculous garb that I did -- a garb that was a work of enchantment, and intended to make the wearer secure from hurt by human hands.
